Abstract
(EN)
Disclosed is an optical imaging lens set, the lens set sequentially comprising, from an object side to an image side and along an optical axis: a first lens (E1), a second lens (E2), a third lens (E3), a fourth lens (E4), a fifth lens (E5), and a sixth lens (E6), which have focal powers. An object-side surface (S1) of the first lens (E1) is a convex surface, and an image-side surface (S2) thereof is a concave surface; an image-side surface (S4) of the second lens (E2) is a concave surface; and an object-side surface (S11) of the sixth lens (E6) is a concave surface. The distance TTL, on the optical axis, from the object-side surface (S1) of the first lens (E1) to an imaging surface of the optical imaging lens set and the half ImgH of the diagonal length of an effective pixel region on the imaging surface of the optical imaging lens set satisfy TTL/ImgH ≤ 1.23.

L'invention concerne un ensemble de lentilles d'imagerie optique, l'ensemble de lentilles comprenant séquentiellement, d'un côté objet à un côté image et le long d'un axe optique : une première lentille (E1), une deuxième lentille (E2), une troisième lentille (E3), une quatrième lentille (E4), une cinquième lentille (E5) et une sixième lentille (E6), qui ont des puissances focales. Une surface côté objet (S1) de la première lentille (E1) est une surface convexe, et une surface côté image (S2) de celle-ci est une surface concave ; une surface côté image (S4) de la seconde lentille (E2) est une surface concave ; et une surface côté objet (S11) de la sixième lentille (E6) est une surface concave. La distance TTL, sur l'axe optique, depuis la surface côté objet (S1) de la première lentille (E1) jusqu’à une surface d'imagerie de l'ensemble de lentilles d'imagerie optique et la moitié ImgH de la longueur diagonale d'une région de pixel effective sur la surface d'imagerie de l'ensemble de lentilles d'imagerie optique satisfont TTL/ImgH ≤ 1,23.
